Inward opening wooden windows EURO 78 are made of selected, knot-free, 3-layer glued timber (78 mm).

Wooden windows EURO 78 can be glazed with up to 42 mm wide 2-3 glass new generation warm glass packages.

According to tests carried out by KTU, the basic window’s thermal insulation index reaches 1.0 W/(m²K).

Like other wooden windows of the EURO profile, EURO 78 has an improved three-intermediate system that not only helps to retain heat but also prevents sound leakage.
